The rest of the syllabus

Question-level mapping for these areas is still being verified. Every official paper covering them is in the year table above.

• Module 5: Equilibrium and Acid Reactions — Static and dynamic equilibrium (reversible reactions, Le Chatelier's principle) · Factors that affect equilibrium (concentration, temperature, pressure, volume, catalysts) · Calculating the equilibrium constant (Kc / Ksp) and its meaning · Acids and bases (Bronsted-Lowry theory, conjugate pairs) · Quantitative analysis (acid-base titrations, pH and pOH calculations)
• Module 6: Acid/Base Reactions — Properties of acids and bases (strong vs weak, monoprotic vs polyprotic) · Using Bronsted-Lowry theory to explain acid/base behaviour · Quantitative analysis of acids and bases (titration curves, indicators) · Applications and uses of neutralisation reactions
• Module 7: Organic Chemistry — Nomenclature and structure of organic compounds (hydrocarbons, functional groups) · Hydrocarbons (alkanes, alkenes, alkynes, addition/substitution reactions) · Products of reactions of organic compounds (alcohols, esters, polymers) · Polymers (addition and condensation polymerisation)
• Module 8: Applying Chemical Ideas — Analysis of inorganic substances (qualitative and quantitative techniques, spectroscopy) · Analysis of organic substances (chromatography, mass spectrometry, NMR) · Chemical synthesis and design (industrial processes, green chemistry)
